- Loading an .mkv with prores+dts inside (previously created by hybrid)
- Want to passthrough video+audio to save it into a new file because it's not yet accepted in topaz ("colorspace error")
- Extraction of video stream fails.
Quote:Error: Extraction of track ID 0 with the CodecID 'V_PRORES' is not supported.
Is an error thrown by mkvextract.
Can't change mkvextract, but maybe I can find a workaround.
Does it work if you enable "Config->Extraction->Stream extraction with ffmpeg"?
can you make sense of this?
extracting doesn't work but frameserving works? mhmok...?
Quote:Nice, I'll adjust Hybrid to automatically use ffmpeg when extracting ProRes from mkv tomorrow.
if it doesn't have any disadvantages ok.. i'm saying this because normally, extracing/passing through prores content is not a problem.. it only seems to become a problem if the prores profile/bit depth is too high.
In one screenshot you are re-encoding and in the other you are re-muxing both seem to work.

Before extraction was done with mkvextract which does not support ProRes. (Mosu, the mkvtoolnix author, probably doesn't use ProRes.
(If you ask for it over at https://gitlab.com/mbunkus/mkvtoolnix/-/issues, Mosu might look into it, or say that he doesn't plan to support it.)
Decoding for the encoding is done through libav.
Extracting with ffmpeg also uses libav.

iirc anything with an alpha channel is not supported by libav/ffmpeg.
Cu Selur
Ps.: uploaded a new dev which does force ffmpeg as demuxer for mkv(ProRes).
